The Omnigenic Model as a Metaphor for Life
The collective intellect is change-blind. Knowledge gained seems so natural that we forget what it was like not to have it. Piaget says children gain long-term memory at age 4 and don't learn abstract thought until ten; do you remember what it was like not to have abstract thought? We underestimate our intellectual progress because every every sliver of knowledge acquired gets backpropagated unboundedly into the past. For decades, people talked about "the gene for height", "the gene for intelligence", etc. Was the gene for intelligence on chromosome 6? Was it on the X chromosome? What happens if your baby doesn't have the gene for intelligence? Can they still succeed? Meanwhile, the responsible experts were saying traits might be determined by a two-digit number of genes. Human Genome Project leader Francis Collins estimated that there were "about twelve genes" for diabetes, and "all of them will be discovered in the next two years". Quanta Magazine reminds us of a 1999 study which claimed that "perhaps more than fifteen genes" might contribute to autism. By the early 2000s, the American Psychological Association was a little more cautious, was saying intelligence might be linked to "dozens – if not hundreds" of genes.

In the Balance
When you first take the Artifact, you will see a vision of ALPHANION, Demon-Sultan of the Domain of Order, who appears as a grid of spheres connected by luminous lines. Alphanion will urge you to use the Artifact to enforce cosmic order, law at its most fundamental. He will show you visions of all the most brutal and sadistic crimes of history, of all the wars caused by nations that could not live together in harmony, and he will tell you they are all preventable. He will show you dreams of perfectly clean cities with wide open streets, where everyone earns exactly the optimal amount of money and public transportation is accurate to the second. He will tell you it is all attainable. But if you hesitate even an instant to take Alphanion's offer, you will see a vision of CTHGHFZXAY, Demon-Shah of the Domain of Chaos, who appears as a shifting multicolored cloud. Cthghfzxay will urge you to use the Artifact to promote cosmic chaos, the ultimate principle of freedom. She will condemn the works of Order as a lie, a dystopia bought at the cost of true human liberty. She will show you visions of primaeval forests, where no two flowers are alike, where each glade holds a new mystery, where people run wild in search of new adventure. She will tell you it can all be yours. As you weigh these two offers, you will see a vision of ZAMABAMAZ, Demon-Pharaoh of the Domain of Balance, who appears as a man and woman conjoined. They will tell you that neither Order nor Chaos is at the root of human flourishing, but an ability to strike the right balance between the two. That a virtuous life is one spent in moderation between total wild liberty and a stifling concept of rote rule-following. That Alphanion and Cthfhfzxay are the two poles of the universe, and that righteousness exists in the space created by their interaction. They will ask you to devote the Artifact and its power to the Domain of Balance, so all people can better manage the interaction of Order and Chaos in their own lives. This will seem reasonable to you, but then there will appear a vision of IYYYYYYYYYYYYYYYYYYYYYYY, Demon-Raja of the Domain of Excess, who appears as a blinding violet light. It will tell you that both Order and Chaos present coherent visions of the world, but that for the love of God, choose one or the other instead of being a wishy-washy milquetoast who refuses to commit to anything. It will tell you that blinding white and pitch black are both purer and more compelling than endless pointless grey. It will ask you to give the Artifact to somebody – anybody – other than Zamabamaz.

[ACC Entry] Should Transgender Children Transition?
[This is an entry to the Adversarial Collaboration Contest by flame7926 and a_reader.] [Content note: suicide, depression, transphobia, self-harm] Transgender childhood transition is a hotly debated topic, with extensive media coverage devoted to it in recent years. (pro: BBC, The Lancet and The New York Times ; contra: The Cut, New Statesman and The Globe and Mail).We see plenty of stories of transgender children (or gender dysphoric children and gender nonconforming children), both in the media and in the blogosphere. As early as 2 or 3, defying the expectations of their family, those children show a persistent and insistent preference for many things associated with the other sex: little boys want long hair and love dresses, Barbie dolls, Disney princesses and mermaids; little girls, instead, dislike stereotypically feminine activities and prefer rough and tumble play, refuse to wear dresses and insist to have their hair shorter and shorter. Sometimes, from the very beginning, the toddler corrects the parents: "I'm a boy /girl!", but more frequently cross-gender behavior is more prevalent. This is only sometimes followed with the child expressing preferences that would be termed gender dysphoria. The child (born and currently living as a as one sex) says to their parents something like "God made a mistake" or "something went wrong in Mommy's tummy" because he should have been a girl, not a boy (or the other way around). The worried parents search information on the internet and seek out the advice of an expert. There, they usually find one or both of these contradicting opinions: Gender-affirming approach Listen to your child – he/she knows best his/her gender. Let your child be his/her true self. It's your responsibility as a parent to support your child in all stages of his/her transition: social transition now, puberty blockers at the beginning of puberty, cross-sex hormones in adolescence, surgery at 18. To oppose it is child abuse. Transphobia costs lives: 41% of transgenders attempt suicide. Do you prefer a happy daughter or a dead son? Or: Therapeutic approach Your child is just confused. He/she is too young to understand gender and to take such important decision. 80% of gender nonconforming children desist. You, as a parent, have the responsibility to correct his/her wrong behavior. If you tolerate it, gender dysphoria will be reinforced by repetition and persist to adulthood. To encourage your child's delusion is child abuse. Transgenders individuals face lifelong struggle and often suffer from poor mental health: 41% of transgenders attempt suicide. Do you really want that for your son, when he could instead come to accept the body he was born with? The first approach is promoted by transgender activists, the second by the conservative media, but both are supported by some experts. The "Gender-affirming approach" is supported by the Dutch team from the Gender Clinic at VU Medical Centre, Amsterdam, who elaborated the typical transition treatment for minors, with puberty blockers at 12 and cross-sex hormones at 16, and, in the US, by Kristina Olson and others from the TransYouth Project. The "Therapeutic approach" is supported by Kenneth Zucker and his team from the Gender Identity Service at Centre for Addiction and Mental Health, Toronto, and, in the US, by Paul McHugh at Johns Hopkins University School of Medicine. There are also experts such as Debra Soh, once a gender nonconforming girl herself, that advise parents to wait and see until adolescence, because in many cases gender dysphoria desists spontaneously, without intervention. Who to believe when the experts disagree? Let's see the evidence.

[ACC Entry] Should Childhood Vaccination Be Mandatory?
This is an entry to the Adversarial Collaboration Contest by Mark Davis and Mark Webb, who sent the following introduction along with their entry: Mark Davis is a naturopathic doctor. Naturopathic medicine is a century-old profession in the United States, but it's small, with fewer than 10,000 NDs licensed to practice naturopathic medicine in the US in 2018. The profession has been historically highly skeptical of vaccination in general, and the modern profession is contentiously split on the topic, with vocal advocates of CDC-scheduled routine childhood vaccination and vocal dissidents both offering continuing medical education for NDs. Mark Davis' main goal in this adversarial collaboration was to argue that there is enough reasonable doubt that routine childhood vaccines could contribute to hyper-inflammatory disease, and enough reduced harm from vaccine-preventable diseases from other medical and public health interventions (in countries with greater economic resources) that parents should be given wide latitude to make individual choices re: routine childhood vaccines despite the clear benefits to individual and public health from preventing those diseases. He became more convinced in his conversations with Mark Webb that widespread childhood vaccination is in the best interest of public health. Mark Webb is a clinical researcher – with a current focus in oncology. He completed a PhD in immunology, specifically focused on the mechanisms driving the development of asthma. Mark Webb's main goal in this collaboration was to argue that atopy and autoimmunity are likely not driven by vaccination, and that this idea is a distraction from finding the real causes of the increase in these diseases. Throughout the collaboration, he was reminded of the nature of safety surveillance with all drugs, and of the sensitive nature of vaccination as a medical intervention. He became persuaded that policy should not just reflect the best evidence currently available, but should also reflect a certain degree of humility that there will always be something we don't know.

[ACC Entry] Are Islam and Liberal Democracy Compatible?
[This is an entry to the Adversarial Collaboration Contest by John Buridan and Christian Flanery.] Matter: To what extent does liberalism and democracy obtain in Islamic countries. Whether Islam consistently poses political opposition to liberalism and democracy. Two simple narratives have split the western world's perspective on Islam. These two narratives do not exhaust the spectrum of opinion, but they do function well enough to establish the basic controversy around Islamic countries and Liberal Democracy. The first narrative opines that Islam is an ideology inimical to "western values," such as classical liberalism and liberal egalitarianism, and a rival to the Judeo-Christian social mores. It constitutes an ideological rival, inherently aggressive, both unable and unwilling to sustain non-partisan legal systems, democratic norms, fair treatment for opposition parties, protection of dissidents, or the basic rights and freedoms which Western European and Anglophone countries enjoy. And that Islam sustains this undesirable state of affairs. The second is that Islam is not qualitatively different from any other religion. Islam has contributed to civilization in a significant way, and ordinary Muslims share our own values of family, peace, and justice. In contrast to the first narrative which stresses Islam as an ideology, the second narrative emphasizes that Muslims are normal people.There is no problem with Islam eo ipso; the perceived "problems" of Islam are actually some combination of the fairly normal problems of traditional societies, poor socio-economic conditions, and legacy problems from colonialism. In order to avoid a point-scoring debate between these two narratives, our approach is to provide a descriptive examination of the performance of liberal democracy within Islamic environments. We take as granted for this paper that one cannot look at a religion on paper and predict what it will look like in a polity. Religious practice and theological doctrine inform every aspect of the pious person's outlook and life, but the way in which it informs that outlook is not deterministic and cannot be gleaned merely by looking at the source texts, nor by the impossible task of a quantitative comparison of which religion has produced more violence across regions and millenia. Although we believe original texts are not deterministic, that does not mean Islam is totally amorphous. Religious culture is a powerful force within society. It unifies people, allows them to feel part of something bigger and better, it provides solace in their troubles, and can mobilize political action. How that mobilization of power occurs remains largely up to the needs of the moment, but it's that mobilization of power which we are interested in.

[ACC Entry] Does the Education System Adequately Serve Advanced Students?
[This is an entry to the Adversarial Collaboration Contest by TracingWoodgrains and Michael Pershan (a k-12 math teacher), on advanced students in the education system] "What do America's brightest students hear? Every year, across the nation, students who should be moved ahead at their natural pace of learning are told to stay put. Thousands of students are told to lower their expectations, and put their dreams on hold. Whatever they want to do, their teachers say, it can wait." – A Nation Deceived, p.3 "There is an apparent preference among donors for studying the needs and supporting the welfare of the weak, the vicious, and the incompetent, and a negative disregard of the highly intelligent, leaving them to "shift for themselves." Hollingworth, 1926 1. Eager to Learn and Underachieving Pretend you're a teacher. With 25 students, who gets your attention during class? There's the kid who ask for it, whose hand is constantly up. There's also the quiet kid in the corner who never says a word, but has been lost in math since October, who will fail if you don't do something. There's the student in the middle of the pack, flowing along. Finally, there's the kid who finishes everything quickly. She's looking around and wondering, what am I supposed to do now? In a survey of teachers from 2008, just 23% reported that advanced students were a top priority for them, while 63% reported giving struggling students in their classes the most attention. A 2005 study found the same trend in middle schools, where struggling students receive the bulk of instructional modification and special arrangements. This was true even while 73% agreed that advanced students were too often bored and under-challenged in school. While teachers, it seems, are sympathetic to the smart bored kid, that's just not a priority for them.

This Week: Adversarial Collaboration Entries
This week I'll be presenting entries from the adversarial collaboration contest. Remember, an adversarial collaboration is where two people with opposite views on a controversial issue work together to present a unified summary of the evidence and its implications. In theory it's a good way to make sure you hear the strongest arguments and counterarguments for both sides – like hearing a debate between experts, except all the debate and rhetoric and disagreement have already been done by the time you start reading, so you're just left with the end result. A few months ago, I asked readers to write adversarial collaborations and submit them to me. After the inevitable flakeouts and disappearances, I got four entries: 1. Does the current US education system adequately serve advanced students? (by Michael Pershan and TracingWoodgrains) 2. Is Islam compatible with liberal democracy? (by John Buridan and Christian Flanery) 3. Should childhood vaccination be mandatory? (by Mark Davis and Mark Webb) 4. Should children who identify as transgender start transitioning? (by a_reader and flame7926) I'm going to post one of these per day. Over the weekend, I'll post a link to a poll where readers can vote for their favorite. I'm also going to vote for my favorite, and my vote will be worth 5% of the total number of reader votes. Whoever gets the most votes wins. The prize is $1000; thanks to everyone who donates to the Patreon for making this possible. Please put any comments about the contest itself here, not on the individual entries.

Bureaucracy as Active Ingredient
Commenters on yesterday's post brought up an important point: sometimes bureaucracies aren't just inefficient information gathering and processing mechanisms. Sometimes they're the active ingredient in a plan. Imagine there's a new $10,000 medication. Insurance companies are legally required to give it to people who really need it and would die without it. But they don't want somebody who's only a little bit sick demanding it as a "lifestyle" drug. In principle doctors are supposed to help with this, but doctors have no incentive to ever say no to their patients. If the insurance just sends the doctor a form asking "does this patient really need this medication?", the doctor will always just check "yes" and send it back. Even if the form says in big red letters PLEASE ONLY SAY YES IF THERE IS AN IMPORTANT MEDICAL NEED, the doctor will still check "yes" more often than a rational central planner allocating scarce resources would like. And insurance companies are sometimes paranoid about refusing to do things doctors say are important, because sometimes the doctor was right and then they can get sued. But imagine it takes the doctor an hour of painful phone calls to even get the right person from the insurance company on the line. Now there's a cost involved. If your patient is going to die without the medication, you'll probably groan and start making the phone calls. But if your patient doesn't really need it, and you just wanted to approve it in order to be nice, now you might start having a heartfelt talk with your patient about the importance of trying less expensive medications before jumping right to the $10,000 one.

Bulls**t Jobs (Part 1 of ∞)
A surprisingly common part of my life: a patient asks me for a doctor's note for back pain or something. Usually it's a situation like their work chair hurts their back, and their work won't let them bring in their own chair unless they have a doctor's note saying they have back pain, and they have no doctor except me, and their insurance wants them to embark on a three month odyssey of phone calls and waiting lists for them to get one. In favor of writing the note: It would take me all of five seconds. I completely believe my patients when they say their insurance is demanding the three month odyssey. Or sometimes they don't have insurance and it would be a major financial burden for them to consult another doctor. Also, I've seen these other doctors and they have no objective test for back pain. 90% of the time they just have the patient stand in front of them, make whatever movement it is that hurts their back, ask the patient if it hurt their back, and when the patient says yes, the doctor says "That's back pain all right, take some aspirin or ibuprofen or whatever". Against writing the note: I am a psychiatrist. I usually treat patients via telemedicine, which means that in many cases I have literally never seen their back. All I remember about back pain from medical school is that some people call it "lumbago", a word that stuck in my head because it sounds like a cryptid or small African nation. I know even less about the ergonomics of chairs, or when people do vs. don't require better ones. Any note I write about back pain and chair recommendations is going to be a total sham, bordering on medical fraud. I could demand my patient take time off work to come in for an examination, sometimes from several hours away, just so I can do the thing where they bend their back in front of me and tell me it hurts. But that's kind of just passing the shamminess a little bit down the line in a way that seriously inconveniences them.
